What is the Cost to Diagnose the Code?

Labor: 1.0

To diagnose the P2090 code, it typically requires 1.0 hour of labor. The specific diagnosis time and labor rates at auto repair shops can differ based on factors such as the location, make and model of the vehicle, and even the engine type. It is common for most auto repair shops to charge between $75 and $150 per hour.

When is the Code Detected?

The Powertrain Control Module (PCM) monitors the VCT circuit for high and low voltage. The test fails if the voltage exceeds a calibrated limit for a calibrated amount of time.

What are Code Possible Symptoms?

  • Engine Light ON (or Service Engine Soon Warning Light)
  • Long engine start

Code P2090 Description

The Camshaft Position (CMP) Actuator system enables the Engine Control Module (ECM) to change the timing of the camshafts while the engine is operating. The CMP actuator solenoid signal from the ECM is Pulse Width Modulated (PWM). The ECM controls the CMP actuator solenoid duty cycle by controlling the amount of solenoid ON time. The CMP actuator solenoid controls the advance or the retard of each camshaft. The CMP actuator solenoid controls the oil flow that applies the pressure to advance or retard the camshafts.
Ignition voltage is supplied directly to the CMP actuator solenoid. The ECM controls the solenoid by grounding the control circuit with a solid-state device called a driver. The driver is equipped with a feedback circuit that is pulled-up to a voltage. The ECM can determine if the control circuit is open, shorted to ground, or shorted to a voltage by monitoring the feedback voltage.
The Diagnostic Trouble Code (DTC) will set if the ECM detects a short to ground in the CMP actuator solenoid circuits for more than 4 seconds or a cumulative of 50 seconds, when the solenoid is commanded OFF.
